Abstract: Intergroup trust is a critical dimension of intergroup relations. Intergroup trust means that during intergroup interaction, people hold a positive anticipation of outgroup member’s behavior and intention, and would like to take corresponding risk. It is mainly determined by social group memberships of two parties. The trust of ingroup members in outgroup members is the major form of intergroup trust. The antecedents of intergroup trust include social group identity, representation of the identity and intergroup contact experience. The approaches of social identity and intergroup contact can increase intergroup trust by changing identity cognition and improving intergroup interaction. In further research, it is necessary to verify the effects of these approaches in solving Chinese realistic intergroup trust problems.

Key words: intergroup trust, ingroup trust, outgroup trust, social identity, intergroup contact
